Special Issue Information

Dear Colleagues,

One of the main challenges for humanity is to ensure the availability of sufficient safe and nutritious food worldwide. Plants, one of the major sources of human food, are continuously threatened by the endless emergence of new diseases caused by pathogens and variable environmental conditions, particularly during the current global warming period. Thus, there is an unceasing need to better understand the basic mechanisms controlling plant immunity and to develop more sustainable and effective strategies for the production of highly disease-resistant next-generation crops.

Ribonucleic acid (RNA), a polymeric molecule assembled as a chain of nucleotides, plays key biological roles in regulating gene expression in all known forms of life. In plants, RNAs—particularly small RNAs, such as microRNAs—are also at the core of the RNA silencing-based defense responses to biotic and abiotic stresses. In addition to plant endogenous RNAs, a large repertoire of RNAs, such as ribozymes, artificial microRNAs, artificial (synthetic) trans-acting small interfering RNAs or CRISPR guide RNAs can be artificially engineered and applied to plants to regulate gene expression and repress pathogenic RNA or DNA and generate disease resistance.

In this Special Issue, I would like to invite research articles and reviews that highlight the key contribution of any form of RNA in generating disease resistance in plants. I expect this collection of articles to open new horizons in the study of RNA as a key player to combat plant diseases and preserve crop production.

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All papers will be peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Plants is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1200 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Transcriptomic Analysis of Orange Fruit Treated with Pomegranate Peel Extract (PGE)

A Pomegranate Peel Extract (PGE) has been proposed as a natural antifungal substance with a wide range of activity against plant diseases. Previous studies showed that the extract has a direct antimicrobial activity and can elicit resistance responses in plant host tissues. In the present study, the transcriptomic response of orange fruit toward PGE treatments was evaluated. RNA-seq analyses, conducted on wounded fruits 0, 6, and 24 h after PGE applications, showed a significantly different transcriptome in treated oranges as compared to control samples. The majority (273) of the deferentially expressed genes (DEGs) were highly up-regulated compared to only 8 genes that were down-regulated. Gene Ontology (GO) and Kyoto encyclopedia of genes and genomes (KEGG) pathway enrichment analysis showed the involvement of 1233 gene ontology (GO) terms and 35 KEGG metabolic pathways. Among these, important defense pathways were induced and antibiotic biosynthesis was the most enriched one. These findings may explain the underlying preventive and curative activity of PGE against plant diseases. Full article

RNAi-Mediated Resistance Against Viruses in Perennial Fruit Plants
Plants 2019, 8(10), 359; https://doi.org/10.3390/plants8100359 - 22 Sep 2019
Abstract
Small RNAs (sRNAs) are 20–30-nucleotide-long, regulatory, noncoding RNAs that induce silencing of target genes at the transcriptional and posttranscriptional levels. They are key components for cellular functions during plant development, hormone signaling, and stress responses. Generated from the cleavage of double-stranded RNAs (dsRNAs) [...] Read more.
Small RNAs (sRNAs) are 20–30-nucleotide-long, regulatory, noncoding RNAs that induce silencing of target genes at the transcriptional and posttranscriptional levels. They are key components for cellular functions during plant development, hormone signaling, and stress responses. Generated from the cleavage of double-stranded RNAs (dsRNAs) or RNAs with hairpin structures by Dicer-like proteins (DCLs), they are loaded onto Argonaute (AGO) protein complexes to induce gene silencing of their complementary targets by promoting messenger RNA (mRNA) cleavage or degradation, translation inhibition, DNA methylation, and/or histone modifications. This mechanism of regulating RNA activity, collectively referred to as RNA interference (RNAi), which is an evolutionarily conserved process in eukaryotes. Plant RNAi pathways play a fundamental role in plant immunity against viruses and have been exploited via genetic engineering to control disease. Plant viruses of RNA origin that contain double-stranded RNA are targeted by the RNA-silencing machinery to produce virus-derived small RNAs (vsRNAs). Some vsRNAs serve as an effector to repress host immunity by capturing host RNAi pathways. High-throughput sequencing (HTS) strategies have been used to identify endogenous sRNA profiles, the “sRNAome”, and analyze expression in various perennial plants. Therefore, the review examines the current knowledge of sRNAs in perennial plants and fruits, describes the development and implementation of RNA interference (RNAi) in providing resistance against economically important viruses, and explores sRNA targets that are important in regulating a variety of biological processes.
